Drivetrain malfunction error

Haval · 09-15-2022, 07:13 AM

Hello guys,

Apologies if this has posted else where but All of sudden I've started getting this drivetrain error and disappears. I've checked the codes that are available to me on BimmerLink but could someone please help me to decipher what these codes mean. I don't want to take to a mechanic just yet but need to make sure I know what's exactly wrong.

4 errors
255B00: Exhaust gas recirculation actuator high pressure, position control: positive control deviation

I was getting this error constantly. After a ton of trial and error, we came to the conclusion that It was my differential pressure switch. It worked and was fine for a few months then the error came back randomly. No one has been able to figure it out at the shop since, so I'm just dealing with it. Its currently not affecting performance so I'm not going to dump any more money into finding the cause. Good luck.
